The Hot Coffee mod is a mod created for the 2005 personal computer port of the 2004 video game Grand Theft Auto: San Andreas by Rockstar North. When installed, it enables access to an otherwise inaccessible part of the game which involves a sex minigame (featuring oral sex with an "invisible" penis and dry humping) with the main character's girlfriend to try to improve the relationship between the two. The name of the mod is derived from the girlfriends' offer for the main character to come into their homes for "coffee" � a euphemism for sex.
Although the "Hot Coffee" minigame was completely disabled and its existence was only highlighted after the release of the mod for the PC version in June 9, 2005[1], the assets for the minigame were also discovered in both the PlayStation 2 and Xbox versions of the game, and people found ways to enable the minigame via console video game hacking tools. By the middle of July 2005, the discovery of the minigame attracted a considerable amount of controversy from lawmakers and politicians, prompting the game to be re-rated as an adult game and pulled from shelves in several retail outlets. An updated version of San Andreas has since been released with the minigame removed indefinitely, allowing the game to regain its original rating. A patch for the original version of the game, which removes the minigame, has also been released
